zynqmp: pm: Add ACPU_FULL and ACPU_HALF clocks in the invalid list
These clocks are marked as invalid in order to prevent Linux from
registering them.
Note that despite clocks being marked as invalid a security issue
still remains in place as there is nothing that prevents the
non-secure world from gating these clocks and that way halt
the whole APU subsystem.
